STOVE.

Specification `of Letters Patent.

Patented Aue'. 26, 191.9.

Application filed March 29, 1919. Serial No. 286,017.

To all whom it may concern Be it known that I, CHARLIE B. SMITH, a citizen of the United States, residing at Kokomo, in the county of Howard and State of Indiana, have invented certain new and useful Improvements in Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to stoves, and aims to provide a simple and inexpensive attachment for a heating stove to facilitate the heat-ing of the air in the room.

A further object is the provision of an air heatingchamber to be disposed within the combustion chamber of the stove and provided with means for the inlet and outlet of air and to support the chamber in place.

With the foregoing and `other objects in View which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure l is a vertical median section of a stove showing the air heating attachment in place.

Fig. 2 is a horizontal section taken on the line 2-*2 of Fig. l.

The attachment can be used on various heating stoves, and the stove illustrated includes the casing or drum 1 forming the combustion chamber, and a stove pipe Q leads upwardly from the top of the casing to the back wall thereof of the outlet of the products of combustion.

In carrying out the invention, there is provided an air heating chamber 3 of Vertically elongated form, and preferably pyramidal in shape, with its walls tapering This chamber 3 is disposed within the combustion chamber adjacent to the rear wall of the casing, and said chamber is provided adjacent to its lower larger end, with a boss 4 having an opening to threadedly receive a nipple 5 that is inserted through an opening in the back wall of the sto-ve, and a nut 6 is threaded on the nipple to clamp the lower portion of the chamber against the back wall. The nipple 5 thus provides an inlet for fresh air, and assists in supporting the chamber in place. The upper smaller end of the chamber has an opening 7 into which is threaded the lower end of a vertical outlet pipe 8 that extends upwardly through the outlet of the stove into the stove pipe 2, and an elbow 9 is secured on the upper end of the pipe 8 for the engagement of the nipple 10 inserted through an opening in the rear wall of the pipe 2. A nut 11 is threaded on the nipple 10 to bear against the pipe and assist in supporting the chamber 3 within the stove.

The device can be readily installed in almost any air heater, and the 'chamber 3 will be heated by the coals, therebyv heating the air within the chamber which will rise and flow out through the pipe 8 and nipple 10, fresh air being admitted through the nipple 5 into the lower larger portion of the chamber which is adjacent to the bed of the fuel so as to efficiently heat the air. The products of combustion will also flow upwardly around and along the walls of the chamber 3 and pipe 8, and will assist in heating the air, so that the present device will enhance the circulation of air and the heating of the room, especially with a small fire or bed of coals. The tapering form of the chamber 3 will serve to increase or force the discharge of heated air through the pipe 8, thereby obtaining a greater circulation through the chamber.

Having thus described the invention, what is claimed as new is 1. The combination with a stove and outlet pipe, of a vertically elongated air heating chamber within the stove below said pipe, an air inlet nipple extending through the wall of the stove and engaging said chamber near the lower end thereof, and an air outlet pipe extending upwardly through the upper end of said chamber into the first named pipe and discharging through the wall thereof.

2. The combination with a stove and its outletpipe, of a. vertically elongated 'air heating chamber within the stove below said pipe, said chamber having a. large lower end and tapering upwardly to a small upper end, an air inlet nipple extending through the wall of the stove and attached toy said chamber In testimony whereof I have signed my near the lower end thereof, an air outlet name to this specification in the presence pipe extending,- upwardly from the upper of two subscribing Witnesses.

end of said chamber into the rst named CHARLIE B. SMITH. pipe, and an air outlet nipple extending Witnesses:

from the upper end of said p'pe through J R. MORGAN,
